Abstract

Andalehis the local name of MorusmacrouraMiq. in West Sumatra, Indonesia. Nowadays, this dioeciously speciesis in endangered situation. The aim of the research is to find out the appropriate combination of plant growth regulator to induce shoot multiplication of explants from male and female trees of andaleh. The plantlets from this research will be used in the next future to conserve this endangered species in vitro and in vivo, especially in preparing parental material in breeding program. Young buds from male and female trees were used as an explants in basal medium Murashige and Skoog supplemented with BAP (0.5, 1.0, 1.5 and 2.0 mg.L-1) in combination with NAA (1.0 mg.L-1 for each). The frequency of bud break was 50 % in MS medium supplemented with BAP (0.5 mg.L-1) and NAA 1.0 mg.L-1 for both source of explants (female and female trees of andaleh) after 3 weeks of culture. Generally, the number of shoot induction was very low. On the other hand, the rate of callus formation was high (100%) in highest BAP concentration (2.0 mg.L-1).

Abstract

The growth and initial development of the plant greatly determines the survival of the plant at the next stage. This initial phase is also the most sensitive phase of abiotic stress. The level of viability and vigor to produce normal sprouts can explain the success of germination. The aim of this research is to study the temperature change to viabilily and vigor in four rice varieties. Research started from January to February 2018 at Seed Technology and Plant Physiology Laboratory Andalas University and Chemistry Laboratory University Of Padang. This research applies Factorial Experiment in Completely Random Design, where the first factor is four levels of rice varieties, Anak Daro, Batang Piaman, Cisokan and Inpari 30. The second factor is temperature level, 28 0C, 32 0C, 36 0C, 40 0C, 44 0C and 48 0C. Viability and vigor decrease when temperature increase. The optimum temperature for rice germination is 28-32 0 C for Anak Daro, 28-36 0 C for Cisokan, at 28 0 C for Batang Piaman and Inpari 30. Anak Daro and Inpari 30 can germinate until 40 0C. The highest vigor index value at 28 0 C in Cisokan and Inpari 30 (89,33 %). At 28-32 0C Cisokan, Batang Piaman and Inpari 30 has been able to germinate on the second day after planting, but Anak Daro can normal germinate on the third day after planting.

Abstract

Climate change impacts increasing temperature, and environmental factors can affect the capacity and rate of seed germination. This study aimed to determine and study the effect of temperature changes on the viability and vigor of brown rice seeds and the morphology of the sprouts produced. The variation of temperature used was 28-400C, and ten genotypes of brown rice seeds used were Pulen Mudiak, Pulen Kandih, Pulen Marapak, Pulen Talao, 64, Sibandung, Silalang, Timbo Abu, Labuah Baru, and Melayu. The results showed that every 10C increase in temperature affects rice germination percentage. The optimum temperature for the germination of ten genotypes of brown rice tested was a temperature range of 28-330C, with a germination value of >80%, the maximum critical temperature 370C and at 38-40 0C no brown rice seeds germinated. Pulen Marapak has the highest maximum growth potential of 90,3% at 280C and 10% at 370C. The increase in temperature also damages brown rice roots and shoots dengan the average root length is 6,7-10,1 cm and shoot length is 8-11,5 cm at 280C.
